Are you able to perhaps do a bit of gardening in exchange for some home made cakes? Can you repair a zip or undertake dressmaking in exchange for some occasional shopping or DIY?
Why not pop up a list of what you can offer/what you want and see if anyone is able to help out? It can be as a one off, or as a regular thing. It really works and can save you loads of money and can help other people too!
Start adding your ideas to this site and see what help is out there for you!
To think that London, or anywhere else for that matter, does not belong to any one demographic
